TcpClient::SendBufferSize Property


Gets or sets the size of the send buffer.

Namespace:   System.Net.Sockets
Assembly:  System (in System.dll)

property int SendBufferSize {
	int get();
	void set(int value);

Property Value

Type: System::Int32

The size of the send buffer, in bytes. The default value is 8192 bytes.

The SendBufferSize property gets or sets the number of bytes that you are expecting to send in each call to the NetworkStream::Write method. This property actually manipulates the network buffer space allocated for send operation.

Your network buffer should be at least as large as your application buffer to ensure that the desired data will be stored and sent in one operation. Use the SendBufferSize property to set this size. If your application will be sending bulk data, you should pass the Write method a very large application buffer.

If the network buffer is smaller than the amount of data you provide the Write method, several network send operations will be performed for every call you make to the Write method. You can achieve greater data throughput by ensuring that your network buffer is at least as large as your application buffer.

The following code example sets and gets the send buffer size.

//sets the send buffer size using the SendBufferSize public property.
tcpClient->SendBufferSize = 1024;

// gets the send buffer size using the SendBufferSize public property.
if ( tcpClient->SendBufferSize == 1024 )
      Console::WriteLine( "The send buffer was successfully set to {0}", tcpClient->SendBufferSize );
